Version Control GIT — a complete, self-contained learning track in 15 modules. It teaches you Git from the first git init to the internals, recovery tools, and fleet-scale practices that DevOps interviews actually probe.
What it assumes: nothing about Git or version control. You only need a Linux machine (or macOS, or WSL on Windows) with a terminal you can open. Every concept is taught before it is used — start at Module 1 and the track never references anything it has not already explained. Where a topic borders another track in this DevOps Learning library — Linux, Bash Scripting, SSL Certificates — the module links you there.
